TIRE-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 461,095, dated October 13, 1891. Application filed February 10,1891. Serial No. 380,915. (No model.)

To all whom, it may concern: site socket C is provided with a gland o, hav- Be it known that I, CHARLES H. EVANS. a ing a central opening-and provided with packcitizen of the United States, residing at Chiing for makinga tight joint around the inner cago, in the county of Cook and State of 1111- pipe D, which is of smaller diameter than the 5 nois, have invented certain new and useful socket C, as shown in Fig. 2.

Improvements in Tire-Heating Devices; and Pipe D is preferably made of brass, and is I do hereby declare the following to be at'ull, provided at its outer end with a lock or stopclear, and exact description of the invention, nut (l, which has its peripheral portion out such as will enable others skilled in the art to away, leaving projecting lugs 11, Fig. 2, so as to which it appertains to make and use the same. to provide for the passage of gas through This invention relates to a circular adjustsocket C and into tube D.

The branch of the X oppopiece 1s bent out at about rlght angles in th middle and then its outer ends are bent at right angles down ward to form the legs. The two portions thus formed are joined at the middle by rivet g. The legs are connected andstrengthened by rods or bars of strapiron j, which are arranged to cross each other and are riveted to the legs, as shown in Fig. 4. The stand or truss made as described is quite strong and durable and can be cheaply made. The four radial bars at the 'top are provided near their outer ends with holes 2', drilled downward for the insertion of pegs or pins to aid in properly centering the tires to be heated. In order to drill the holes arcs should be struck from the center at g, with radii of one foot nine inches, one foot eleven inches, two feet one inch, and two feet three inches, and the.hole drilled at such points. The stand will be of sufficient size to conveniently support tires ranging from three feet six inches to four feet six inches. For the purpose of heating the various-sized tires the burner-tubes or the curved burnerpipes D and their supply-pipes D are adjusted out or in within the socket C, as will be readily understood, and the parts can be.

manipulated by any unskilled workmen. Instead of a screw-threaded nut cl applied to the outer end of pipe D, such pipe may be provided simply with outwardly projecting lugs or pins for centering and guidingitin socket O.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a tire-heating device, a circular gaspipe, in combination with adjustable burnerheads, substantially as described.

2. In a tire-heating device, a circular gaspipe,in combination with adjustable burnerheads having curved burner-pipes and adapted to be moved outward and inward in relation to the circular gas-pipe.

3. In a tire-heating device, the circular gaspipe, in combination with the burner-heads projecting inwardly therefrom and having curved burner-pipes provided on their inner sides with tips or openings for the gas-flame, substantially as described.

4:. In combination with the circular gaspipe, the burner-heads, each composed of a socket or sheath and an inner sliding pipe having'at its inner end a curved burner-pipe, substantially as described.

5. The combination, with the gas-supply pipe, of a socket or sheath closed at its outer end and having a gland with packing at its inner end, and the inner pipe passing through such gland and into the socket and having lugs or pins at its outer end and a curved burner-pipe at its inner end, substantially as described.

6. The circular gas-pipe composed of curved sections connected by X-couplings, in combination with the burner-heads provided with sockets, and an interior sliding pipe having at its outer end a curved burner-pipe, substantially as described.

7. In combination with the circular gaspipe and burner-heads, the enlarged air-mixing chamber and the gas-supply pipe having a jet-nozzle entering such mixing-chamber, substantially as described.

8. In combination with the circular gaspipe provided with burner-heads, the stand or truss for supporting the tires, provided with means for centering the tires within the burner-heads, substantially as described.

9. In combination with the tire-heating device, the stand or truss composed of the bent bars of angle-iron forming radial bars or rods at the top and legs at the corners, connected together by brace rods or bars, substantially as described.

In testimony whereofl affix my signature in presence of two witnesses.

CHARLES H. EVANS.
